The correct Answer is:
To solve the question regarding the small, red-colored follicular bodies found in the 4th, 5th, and 6th segments of earthworms, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Location**: The question specifies that the small red-colored follicular bodies are located in the 4th, 5th, and 6th segments of the earthworm, above the pharyngeal mass and connected with the pharyngeal glands. 2. **Recall the Function**: These bodies are involved in the formation of blood components. It is essential to understand the role of different glands in earthworms. 3. **Consider the Options**: The question hints at specific types of glands: - **Blood Glands**: Known to be involved in blood formation. - **Septal Glands**: Associated with septal nephridia, found in the 15th and 16th segments. - **Salivary Glands**: Located in the 3rd and 4th segments, also known as dorsal pharyngeal glands. - **Nephridia**: Present in various segments but do not match the description of red-colored follicular bodies. 4. **Eliminate Incorrect Options**: - Septal glands do not match the segment location. - Salivary glands are not red-colored follicular bodies and are located in different segments. - Nephridia types do not correspond to the description of small red bodies. 5. **Conclude with the Correct Answer**: Since the only option that fits the description of small, red-colored follicular bodies in the specified segments is the **Blood Glands**, we conclude that the answer is blood glands. ### Final Answer: **Blood Glands** ---
